REVERSIBLE RUBBISH-BURYING TURNING PLOW.

Application filed February To all whom it may concern:

Be it known that 1, CHARLES H. LOGAN, a citizen of the United States of America, residing at Monette, inthe county of Craighead, State of Arkansas, have invented certain new and useful Improvements in Reversible Rubbish-Burying Turning Plows, of which the following is a specification.

This invention relates to plows, and more particularly stated contemplates the production of a reversible rubbish burying and turning plow.

An object of the present invention is to to producea comparatively simple and dur- 1 ably constructed plow which can be easily handled by one man and readily converted into a, right or left hand plow as will be understood.

With these and other. objects in view the invention further consists in the arrangement and construction of the several parts hereinafter described and pointed out in the appended claims.

In the accompanying drawingsillustrating an embodiment of my invention, and wherein similar reference characters designate corresponding parts in the several views:

Fig. 1 is a perspective view of the plow;

Fig. 2 is a sectional elevation thereof;

Fig. 3 is a detail horizontal sectional view on the line 3-3 of Fig.1;

Fig. 4: is a detail vertical sectional view through the disk mold board and its connection; and

Fig. 5 is a detail plan viewillustratl ng the adjustable connection of the rubbish burying arms.

The present invention has been designed 10, 1921. Serial No.443,912.

with a view to embodying in an agricultural implement features for treating the soil and preserving the fertility of same by properly locating the furrows and burying the rubbish containing humus as may be contained for example in cotton stalks. The invention comprises among other things a centrally located adjustable standard to the ends of which are connected plow shares; a movable mold board in the form of a disk; and means for permitting the rotation of the beam of the plow about the standard thereby shifting the aforesaid disk for cooperative action with the respective plow shares.

Referring to the drawings, the beam 1 may be of usual construction and is provided with a depending spindle 2 at the rear end thereof. The spindle 2 is rotatably mounted in a bearing 3 formed on the supporting standard 4. The nut 5 threaded upon the lower end of'the spindle 2 serves to retain the spindle in the bearing as will be understood. 7 I

Projecting from the upper end of the standard 4 and bearing 3 are segments 6 and 7. These segments are diametrically located, the teeth 8 of which are adapted to receive a locking dog 9. The locking dog 9 is pivoted at 10 to abracket 11. :The bracket 11 extends from an intermediate body portion 12 provided between the beam 1 and the spindle 2-. As shown the body portion 12 and the spindle or shaft2 are formed integral. A shoulder 13 is formed'on this intermediate body portion 12 and is designed to bear against the upper surface of the segments 6 and 7. Secured to or formed integral as shown with the body portion 12 is a segmental gear 14-, the teeth of which are designed to mesh with a similar segmental gear 15, secured to the upper end of the shaft or spindle '16, to the lower end of which latter is connected the disk 17, to be presently described.

The locking dog 9 is shown as engaging the teeth 8 of the segment 7 and is held in place by means of a spring 18 as best shown in Fig. 2. An operating device in the form of a flexible rod or cable 19 is attached at 20 to the end of the locking dog 9. Thiscable extends over a roller 21 provided intermediate the handles of the plow and extends rearwardly to a controlling finger lever 22. The lever 22 is pivoted at 23 to one of the handles, and in proximity to ,the handgrip ping portion thereof. Itwill-be seen irom this construction that upon moving thelever filtere thel en l r p; the l e ina eg? ll e. ted. a nst .thea-fiens ent e spring 18 clear of the segment 7. lzVhen in this released position the beam 1 is free to move about the standard 4 aswillibehereinafter further referred to.

The standard 4 is in the form of a plate having a seriesof perforations 24 therein arrangedto register witha series of similar perforations"'25dormed in the upstanding portion of the plow bar 27. Belt and nut connections 28 serve to adjustably secure the standard 4 and upstanding portion 26 together as shown, thereby regulating the in the bearing 35." The ends of the shaft are preferably reduced and threaded and receive retaining nuts 36 (see Fig. 4). A plate 37 extends from the, bearing and i is provided with a series of holes 38 adapted to adjustably register with a series of Openings 39 formed in a plate 40. Theplate 40 is carried an extension ll-through which the shaft 16fpasse's. The shaft 16-is also mounted iii the bearing 42 formed on one end oli' the web;43 forming the intermediate connection between the plow standard 4 and the disk support. By this construction the disk can beadjusted in'a horizontal plane toward and away from the plow shares. The vertical adjustment of the standard also provides for the substitution oflargerdisks in malcii'ig broader furrows with .greater depth,' aswillbe understood.

A rubbish burying device 44 is carried by the beam 1, and comprises laterally and longitudinally extending arms 45. The arms 45 are positioned for engagement with the' growthfrequently found upon the *soil, and serves to turn the same over into the furrow as will "be understood.

Thearms 45 are adjustablypivoted at 46, one of said arms having a notched segment 47 and the other of said arms being rovided with an engaging latch 48. The latch 48 is retractible byimeans of the operating device 49', thereby serving to position the:

arms 45 at varying distances from the beam 1. The rubbish burying arms 45 are also movable toward and away from the disk 17.

ed. upon. a .stub. shaft: .55.

The -means for eflectingthis rocking. movement comprises a shaft 50 seoured 'to the beam 1. A projecting arm 52 extends up wardly from the shatt 5G, and has-secured thereto one end o'f a spring. 53,. Theopposite end of the spring 53. is attachedto an overhanging rocker arm 54 movably mount- The stub shaft 55 projects from the upstanding plate 56 vformed integr-al with one of the bearings 51 as shown. The plate 56 is provided with a series of notches 57 at. either side'thereof. A central notch 58 is also formed in-said plate and is designed to receive a locking dog 59 carried by the operating handle 60.

A hand gripping device 61 is provided-on T the handle '60 and serves -to -release the lockingdog 59, and permit;ofitsuengagement with the respective notches-57 as will be understood.

The rubbish burying deviceis operated by moving the handle wto1either side-:of-the plow beam, thereby rocking the. upstanding and overhanging arm 54. Through the spring connection 53..and extension 52 the shaft 50 is rotated, .and the respective rub-- bish burying arms 45 .areeither brought toward or moved away from the dislrl7 as willbe understood. The engagement of the lockingdog-59 with eithersetiof notches 57 serves to retain the-rubbishiburying arms. in 1 their adjusted. position. The Y foregoing :construction of rubbish;buryingudeviceforms no part of myipresent invention, thesame being set forth in--U.- S. Letters PatentNo. 1,264,101, granted to '1neu4tpril 23, 1,918.

The usual handles "62. areiattached to the beam 1, anda :suitableaclevis connection 63 lronay be provided attheuotheriend of the eam.-

In operatiomand'more especial-1yv whenit Y is desiredto reverse the plow at the end of a furrow, the locking dog 9, is releasedfrom the segment 7 thereby permitting-thebeam 1 and more especially thepintleQ to rotate in the-bearing 3. .As theibeam 1. is swungv the segmental gear 14 serves to revolve the -meshing segmental gear 15, and shift the disk 17. When the beam; has been. swung the-desired distance,-the looking; dog 9 is dropped into the teeth 8 off thesegment 6,1

andthe .plow is in reversed position for pro- .ducing the succeeding furrow. -Therubbish burying device is adjusted according. to the growth of the soil as will be understood.

From. the foregoing construction it will be seen that I: have produced a readily usable right or left hand plow in which. the disk 17 becomes effective as the mold board when moved-in .eitherdirection. ;.It will also be obvious that a minimum resistance of the trailing plowshareqis afforded and the usual complicated and retarding portions 0'! the now known devices have beeneliminated.

Various'changes in the formand construction of the several parts may be resorted to and I do not limit myself to the exactconstruction herein disclosed.

I claim:

1. A reversible plow including in combination a beam, means for pivotally mounting the beam, said means including a standard, plow shares provided on said standard, a disk associated with said plow shares, said plow shares being vertically adjustable with relation to the beam and disk, and means for shifting said disk with relation to the plow shares upon reversing the plow.

2.
